In order to carry out the provisions of this Chapter, there are hereby created and established certain zones which include all of the land lying beneath the APPROACH SURFACES, TRANSITIONAL SURFACES, HORIZONTAL SURFACES and CONICAL SURFACES as they apply to the GREELEY-WELD COUNTY AIRPORT. Such zones are shown on the GREELEY-WELD COUNTY AIRPORT Airspace (FAR Part 77 Surface), being Exhibit IV of the document entitled, "Airport Master Plan," dated December 15, 2003, a copy of which is on file at the Clerk to the Board's office and the Department of Planning Services. An area located in more than one (1) of the following zones is considered to be only in the zone with the more restrictive HEIGHT limitation. The various zones are hereby established and defined as follows:
A.
Utility Runway Visual Approach Zone: The inner edge of this APPROACH ZONE coincides with the width of the PRIMARY SURFACE and is two hundred fifty (250) feet wide. The APPROACH ZONE expands outward uniformly to a width of one thousand two hundred fifty (1,250) feet at a horizontal distance of five thousand (5,000) feet from the PRIMARY SURFACE. Its centerline is the continuation of the centerline of the RUNWAY.
B.
Runway Larger Than Utility Visual Approach Zone: The inner edge of this APPROACH ZONE coincides with the width of the PRIMARY SURFACE and is one thousand (1,000) feet wide. The APPROACH ZONE expands outward uniformly to a width of one thousand five hundred (1,500) feet at a horizontal distance of five thousand (5,000) feet from the PRIMARY SURFACE. Its centerline is the continuation of the centerline of the RUNWAY.
C.
Precision Instrument Runway Approach Zone: The inner edge of this APPROACH ZONE coincides with the width of the PRIMARY SURFACE and is one thousand (1,000) feet wide.

(Weld County Code Ordinance 2019-02)
Within the COUNTY there are areas subject to unstable geologic conditions which may cause serious damage to properties and may endanger the safety of residents in such areas. The imprudent USE and occupation of these areas will pose a continuing danger to life and property, unless appropriate land USE measures are implemented.
The purpose and intent of the Geologic Hazard Overlay District regulations shall be to:
A.
Minimize hazards to public health and safety or to property in GEOLOGIC HAZARD AREAS.
B.
Promote safe USE of GEOLOGIC HAZARD AREAS.
C.
Reduce the adverse impact of GEOLOGIC HAZARDS on life and property by:
1.
Requiring land USES permitted in GEOLOGIC HAZARD AREAS to be protected from GEOLOGIC HAZARDS by providing for GEOLOGIC HAZARD investigation and the mitigation of the adverse impacts of GEOLOGIC HAZARDS at the time of initial construction.
2.
Regulating the manner in which STRUCTURES designed for human occupancy may be constructed so as to prevent danger to human life or property within such STRUCTURE.
D.
Protect the public from the burden of excessive financial expenditures caused by damage from GEOLOGIC HAZARDS by regulating land USES within GEOLOGIC HAZARD AREAS.
(Weld County Code Ordinance 2019-02)
The regulation of a GEOLOGIC HAZARD AREA by the Overlay regulations does not constitute an affirmation by the COUNTY that lands outside the regulated area as defined on maps adopted by the Board of County Commissioners will be free from the GEOLOGIC HAZARD.
(Weld County Code Ordinance 2019-02)
The soils report submitted with the building permit application shall include geotechnical recommendations stamped by a registered engineer and shall be submitted to the Building Department along with the building permit application. The study shall specify that the foundation and STRUCTURE design are appropriate for the specific site.

All USES permitted within the underlying zone district shall be permitted within HISTORIC TOWNSITES, subject to the requirements of this Division 5.
(Weld County Code Ordinance 2018-03)
A.
Building permits. The COUNTY will not issue a building permit for any STRUCTURE located within a HISTORIC TOWNSITE that enters the SETBACK or OFFSET established for the underlying zone district, or extends over LOT lines. A building permit application within a HISTORIC TOWNSITE shall require submission of a plot plan. No building permit shall be final, nor shall any certificate of occupancy be provided until an Improvements Location Certificate (ILC) is submitted. COUNTY staff shall verify that all STRUCTURES were constructed in substantial compliance with the plot plan. To obtain a building permit for a DWELLING UNIT in a HISTORIC TOWNSITE, the applicant must show the following:
1.
The water supply is adequate in terms of quality, quantity and dependability. Wells on individual LOTS are permitted with well permits issued by the Colorado Division of Water Resources, when PUBLIC WATER is not reasonably available to the property.
2.
Adequate sewer or septic service is available to serve the uses permitted. The sewer service shall comply with the requirements of the applicable zone district and the Weld County Department of Public Health and Environment (WCDPHE).
3.
Access is or can be made available that provides for safe ingress and egress to a public road. All accesses shall be constructed in accordance with the requirements set forth in this Code.
4.
Construction of all internal roads of the HISTORIC TOWNSITE may only occur pursuant to a Right-of-Way Use Permit issued by the Department of Public Works in accordance with this Code, to ensure positive drainage and to avoid conflicts regarding location of utilities.
5.
The LOT is at least two and one-half (2.5) acres in size with an individual well and Onsite Wastewater Treatment System (OWTS), or at least one (1) acre in size with a PUBLIC WATER supply and OWTS. A building permit for a LOT within a HISTORIC TOWNSITE which is smaller than two and one-half (2.5) acres in size on an individual well and OWTS or smaller than one (1) acre in size on a PUBLIC WATER supply may be approved by the COUNTY upon a review and determination by the WCDPHE that the LOT is capable of adequately accommodating the individual well and OWTS, as applicable. For the review by the WCDPHE, the applicant must provide:
a.
A soils evaluation noting soils type in concurrence with the On-site Wastewater Treatment System (OWTS) regulations set forth in Chapter 30 of this Code;
b.
A plot plan/site plan noting proposed well locations (both onsite and on adjacent properties);
c.
Proposed septic system locations and any other applicable setbacks, such as property lines, irrigation ditches, water bodies, water lines, easements and right-of-way, dwellings, cut banks, dry gulches, and intermittent water bodies;
d.
As requested by the WCDPHE, a master site plan of the HISTORIC TOWNSITE showing locations of wells and septic systems or a site plan showing locations of wells and septic systems on adjacent properties within the HISTORIC TOWNSITE; and
e.
If requested by the WCDPHE, a septic envelope and/or well envelope.
6.
As a condition of approval of a building permit within a HISTORIC TOWNSITE, the applicant shall be required to obtain an approved Road Access Permit, pursuant to the provisions set forth in this Code. Application for a Road Access Permit to a resubdivided LOT within a HISTORIC TOWNSITE shall include acknowledgement by the applicant that:
a.
The platted STREET or road of the HISTORIC TOWNSITE from which access is sought will not be maintained by the COUNTY unless it is brought up to the standards and authorized for maintenance as set forth in this Code.
b.
Access from the HISTORIC TOWNSITE onto a State Highway requires the issuance of an access permit by the Colorado Department of Transportation, which may also require the applicant to obtain a traffic study.
B.
Resubdivision.
1.
Resubdivision within a HISTORIC TOWNSITE may be necessary to combine LOTS, change interior LOT lines, incorporate vacated RIGHTS-OF-WAY into LOTS, vacate property from a HISTORIC TOWNSITE, vacate RIGHTS-OF-WAY, or create additional LOTS, subject to the requirements of Chapter 24, Article IX of this Code and this Division 5.
2.
In addition to the requirements and procedures for resubdivision provided in Chapter 24, Article IX of this Code, the following statement shall be included as a note on the resubdivision plat of property located within a HISTORIC TOWNSITE:
Historic Townsites are an important part of Weld County's history, culture, and economy. These subdivisions were created in the late 19th and early 20th centuries. Persons moving into Historic Townsites must recognize and accept there are potential drawbacks in Historic Townsites that may not be present in modern subdivisions, including concerns related to stormwater drainage, water supply limitations, setbacks between wells and septic systems, road access, and road maintenance. Weld County does not maintain internal roads within Historic Townsites unless expressly authorized by resolution of the Board of County Commissioners.
C.
NONCONFORMING STRUCTURES. To the extent that it does not meet the requirements of this Division 5, any STRUCTURE for which the COUNTY has issued a final building permit or certificate of occupancy, located on any LOT or group of LOTS deeded together within a HISTORIC TOWNSITE, shall be considered a NONCONFORMING STRUCTURE. Without resubdividing, the owner of a NONCONFORMING STRUCTURE within a HISTORIC TOWNSITE may receive building permits for the following, as long as such work does not extend into the SETBACK or OFFSET and does not cross LOT lines:
1.
Repairs, restorations or additions to such STRUCTURE, as long as such repairs, restorations or additions comply with the requirements of Section 23-7-40 of this Code, or;
2.
Construction of ACCESSORY BUILDINGS that comply with the ACCESSORY USE requirements of the underlying zone district.
Alternatively, the property owner may apply for resubdivision of the property in accordance with Chapter 24, Article V of this Code, and then may apply for building permits.

b.
The applicant shall demonstrate to the Department of Planning Services that the maximum possible landscaping was preserved or relocated through the DEVELOPMENT process.
5.
Whenever the USE of the property to be developed or redeveloped will conflict with the USE of adjoining property, there shall be an opaque planted screen between the two (2) properties. The screen shall moderate the impact of noise, light, aesthetic concerns, and traffic.
6.
Fescue, brome/fescue, or other turf types shall be used in lieu of bluegrass where heavy foot traffic is not anticipated.
7.
LANDSCAPED areas shall be configured to maximize interconnectivity within the site to natural areas and landscaped areas within existing or future adjacent DEVELOPMENT. Small isolated islands of landscaping, except as required in PARKING LOTS and for screening along roadways, shall be avoided. Open space shall be provided where significant natural features exist.
B.
Landscaping requirements for parking lots.
1.
At least ten percent (10%) of the area of a PARKING LOT shall be landscaped if the PARKING LOT contains ten (10) or more spaces. PARKING LOTS with fewer than ten (10) parking spaces shall include landscaping on at least five percent (5%) of the PARKING LOT area. At least seventy-five percent (75%) of the required LANDSCAPE area shall include living plant material. Generally, every tenth (10th) parking space should be delineated with a planting island. Trees planted in PARKING LOTS shall be either in bays or planting islands of at least five (5) feet by five (5) feet. Trees should be distributed throughout the parking area; however, they shall be placed so they do not obstruct visibility for cars and pedestrians.
2.
Berming and shrub or tree planting shall be used to screen PARKING LOTS from view of the ADJACENT STREETS/ROADS. Berms may vary in height, depending on location and proximity of existing trees, but shall have smooth transitions from the top of the curb to the SETBACK line so as to not create snow traps. Grading of berms shall not be lumpy or abrupt.
3.
Landscaping techniques shall be used to alleviate the harsh visual appearance that accompanies PARKING LOTS. At least seventy-five percent (75%) of the length of the frontage of the PARKING LOT must be effectively SCREENED.
4.
Loading, service, or storage areas shall be SCREENED with an opaque screen that is an integral part of the BUILDING architecture. Chain-link fencing with slats, fabric, or pallets is not an acceptable screening material. Plant material shall be used to soften the appearance of the screen.
C.
Landscaping requirements along roadway corridors.
1.
Plantings along roadways shall be integrated with the landscaping of the rest of the site.
2.
A minimum LANDSCAPE SETBACK in accordance with Table 23.5 below shall be included, to be measured from the existing or future RIGHT-OF-WAY at right angles to the STREET/ROAD towards the interior of the LOT. The LANDSCAPE SETBACK shall include five (5) shrubs (minimum size of five-gallon container) plus either one (1) shade tree with a minimum two-and-one-half-inch-caliper (measured six (6) feet above the surrounding ground) or one (1) coniferous tree with a minimum height of six (6) feet for every forty (40) feet of STREET/ROAD frontage. A mix of coniferous and deciduous trees and shrubs shall be clustered or grouped to avoid straight lines, with a maximum distance of one hundred (100) feet between trees or groupings. The effectiveness of the screening along I-25 and State Highway 119 shall be increased by planting trees and shrubs in layered beds (two (2) or more rows of plant material rather than a single row). No parking, storage, fencing, or other STRUCTURES shall be permitted within the LANDSCAPE SETBACK.

(Weld County Code Ordinance 2020-15)
Located within the A (Agricultural) Zone are properties listed on the National Register of Historic Places and recognized by resolution of the Board of County Commissioners of Weld County as "Agricultural Heritage Sites." Agricultural Heritage Sites may be owned by private citizens, private corporations or by non-profit corporations. The National Register of Historic Places listings recognize that the Agricultural Heritage Sites have historic significance typically because of a long and unique history of agricultural activities having taken place thereon. The Board of County Commissioners finds that Agricultural Heritage Sites must be preserved for future generations and not be subject to eminent domain proceedings brought by Weld County intending to acquire rights-of-way for road improvements, unless such acquisitions are agreed to by the owners of the Agricultural Heritage Sites.
The purpose and intent of the Agricultural Heritage Overlay District shall be to preserve and protect Agricultural Heritage Sites located in the A (Agricultural) Zone and listed on the National Register of Historic Places from eminent domain proceedings brought by Weld County to acquire rights-of-way for road improvements, unless such acquisitions are agreed to by the owner(s) of the Agricultural Heritage Sites.
There is hereby established in the Weld County A (Agricultural) Zone an Agricultural Heritage Overlay District. The Agricultural Heritage Overlay District includes all lands which have been listed on the National Register of Historic Places because of their long and unique history of agricultural activities having taken place thereon and which have been designated as Agricultural Heritage Sites by resolution(s) of the Board of County Commissioners.
All USES permitted within the A (Agricultural) Zone District as Uses by Right, Accessory Uses, permitted uses (ZPAG's), or Uses by Special Review (USR's) shall be permitted on an Agricultural Heritage Site.
For a property located in the A (Agricultural) Zone which is listed on the National Register of Historic Places to come within the Agricultural Heritage Overlay District and thereby authorized to take advantage of the protections detailed in Section 23-5-550, below, it must be designated as an Agricultural Heritage Site by resolution of the Board of County Commissioners.
Agricultural Heritage Sites within the Agricultural Heritage Overlay District shall not be subject to eminent domain proceedings by Weld County to acquire rights-of-way for road improvements, unless such acquisitions are agreed to by the owner(s) of the Agricultural Heritage Sites.

(Weld County Code Ordinance 2018-03)
A.
Building permits. The COUNTY will not issue a building permit for any STRUCTURE located within a HISTORIC TOWNSITE that enters the SETBACK or OFFSET established for the underlying zone district, or extends over LOT lines. A building permit application within a HISTORIC TOWNSITE shall require submission of a plot plan. No building permit shall be final, nor shall any certificate of occupancy be provided until an Improvements Location Certificate (ILC) is submitted. COUNTY staff shall verify that all STRUCTURES were constructed in substantial compliance with the plot plan. To obtain a building permit for a DWELLING UNIT in a HISTORIC TOWNSITE, the applicant must show the following:
1.
The water supply is adequate in terms of quality, quantity and dependability. Wells on individual LOTS are permitted with well permits issued by the Colorado Division of Water Resources, when PUBLIC WATER is not reasonably available to the property.
2.
Adequate sewer or septic service is available to serve the uses permitted. The sewer service shall comply with the requirements of the applicable zone district and the Weld County Department of Public Health and Environment (WCDPHE).
3.
Access is or can be made available that provides for safe ingress and egress to a public road. All accesses shall be constructed in accordance with the requirements set forth in this Code.
4.
Construction of all internal roads of the HISTORIC TOWNSITE may only occur pursuant to a Right-of-Way Use Permit issued by the Department of Public Works in accordance with this Code, to ensure positive drainage and to avoid conflicts regarding location of utilities.
5.
The LOT is at least two and one-half (2.5) acres in size with an individual well and Onsite Wastewater Treatment System (OWTS), or at least one (1) acre in size with a PUBLIC WATER supply and OWTS. A building permit for a LOT within a HISTORIC TOWNSITE which is smaller than two and one-half (2.5) acres in size on an individual well and OWTS or smaller than one (1) acre in size on a PUBLIC WATER supply may be approved by the COUNTY upon a review and determination by the WCDPHE that the LOT is capable of adequately accommodating the individual well and OWTS, as applicable. For the review by the WCDPHE, the applicant must provide:
a.
A soils evaluation noting soils type in concurrence with the On-site Wastewater Treatment System (OWTS) regulations set forth in Chapter 30 of this Code;
b.
A plot plan/site plan noting proposed well locations (both onsite and on adjacent properties);
c.
Proposed septic system locations and any other applicable setbacks, such as property lines, irrigation ditches, water bodies, water lines, easements and right-of-way, dwellings, cut banks, dry gulches, and intermittent water bodies;
d.
As requested by the WCDPHE, a master site plan of the HISTORIC TOWNSITE showing locations of wells and septic systems or a site plan showing locations of wells and septic systems on adjacent properties within the HISTORIC TOWNSITE; and
e.
If requested by the WCDPHE, a septic envelope and/or well envelope.
6.
As a condition of approval of a building permit within a HISTORIC TOWNSITE, the applicant shall be required to obtain an approved Road Access Permit, pursuant to the provisions set forth in this Code. Application for a Road Access Permit to a resubdivided LOT within a HISTORIC TOWNSITE shall include acknowledgement by the applicant that:
a.
The platted STREET or road of the HISTORIC TOWNSITE from which access is sought will not be maintained by the COUNTY unless it is brought up to the standards and authorized for maintenance as set forth in this Code.
b.
Access from the HISTORIC TOWNSITE onto a State Highway requires the issuance of an access permit by the Colorado Department of Transportation, which may also require the applicant to obtain a traffic study.
B.
Resubdivision.
1.
Resubdivision within a HISTORIC TOWNSITE may be necessary to combine LOTS, change interior LOT lines, incorporate vacated RIGHTS-OF-WAY into LOTS, vacate property from a HISTORIC TOWNSITE, vacate RIGHTS-OF-WAY, or create additional LOTS, subject to the requirements of Chapter 24, Article IX of this Code and this Division 5.
2.
In addition to the requirements and procedures for resubdivision provided in Chapter 24, Article IX of this Code, the following statement shall be included as a note on the resubdivision plat of property located within a HISTORIC TOWNSITE:
Historic Townsites are an important part of Weld County's history, culture, and economy. These subdivisions were created in the late 19th and early 20th centuries. Persons moving into Historic Townsites must recognize and accept there are potential drawbacks in Historic Townsites that may not be present in modern subdivisions, including concerns related to stormwater drainage, water supply limitations, setbacks between wells and septic systems, road access, and road maintenance. Weld County does not maintain internal roads within Historic Townsites unless expressly authorized by resolution of the Board of County Commissioners.
C.
NONCONFORMING STRUCTURES. To the extent that it does not meet the requirements of this Division 5, any STRUCTURE for which the COUNTY has issued a final building permit or certificate of occupancy, located on any LOT or group of LOTS deeded together within a HISTORIC TOWNSITE, shall be considered a NONCONFORMING STRUCTURE. Without resubdividing, the owner of a NONCONFORMING STRUCTURE within a HISTORIC TOWNSITE may receive building permits for the following, as long as such work does not extend into the SETBACK or OFFSET and does not cross LOT lines:
1.
Repairs, restorations or additions to such STRUCTURE, as long as such repairs, restorations or additions comply with the requirements of Section 23-7-40 of this Code, or;
2.
Construction of ACCESSORY BUILDINGS that comply with the ACCESSORY USE requirements of the underlying zone district.
Alternatively, the property owner may apply for resubdivision of the property in accordance with Chapter 24, Article V of this Code, and then may apply for building permits.

b.
Siberian elm (Ulmus pumila).
c.
Chinese elm (Ulmus parvifolia).
d.
Tree of Heaven (Ailanthus altissima).
e.
NOXIOUS WEEDS.
4.
BUILDINGS and PARKING LOTS shall be located to preserve and promote the health of existing trees. The applicant shall be responsible for locating and preserving, where feasible, all individual trees of four-inch caliper or larger in size (measured six (6) feet above the surrounding ground) and massed groups of three (3) or more smaller trees. Before construction, the following precautions shall be taken to preserve quality trees:
a.
The applicant shall submit to the Department of Planning Services a detailed Landscape Plan delineating the existing and proposed trees, shrubs, groundcovers, and natural features, such as rock outcroppings and other landscaping elements. The Plan shall show where landscaping exists or will be located, along with planting and construction details. Where existing plantings are to be retained, the applicant shall include in the plans proposed methods of protecting the plantings during construction.
b.
The applicant shall demonstrate to the Department of Planning Services that the maximum possible landscaping was preserved or relocated through the DEVELOPMENT process.
5.
Whenever the USE of the property to be developed or redeveloped will conflict with the USE of adjoining property, there shall be an opaque planted screen between the two (2) properties. The screen shall moderate the impact of noise, light, aesthetic concerns, and traffic.
6.
Fescue, brome/fescue, or other turf types shall be used in lieu of bluegrass where heavy foot traffic is not anticipated.
7.
LANDSCAPED areas shall be configured to maximize interconnectivity within the site to natural areas and landscaped areas within existing or future adjacent DEVELOPMENT. Small isolated islands of landscaping, except as required in PARKING LOTS and for screening along roadways, shall be avoided. Open space shall be provided where significant natural features exist.
B.
Landscaping requirements for parking lots.
1.
At least ten percent (10%) of the area of a PARKING LOT shall be landscaped if the PARKING LOT contains ten (10) or more spaces. PARKING LOTS with fewer than ten (10) parking spaces shall include landscaping on at least five percent (5%) of the PARKING LOT area. At least seventy-five percent (75%) of the required LANDSCAPE area shall include living plant material. Generally, every tenth (10th) parking space should be delineated with a planting island. Trees planted in PARKING LOTS shall be either in bays or planting islands of at least five (5) feet by five (5) feet. Trees should be distributed throughout the parking area; however, they shall be placed so they do not obstruct visibility for cars and pedestrians.
2.
Berming and shrub or tree planting shall be used to screen PARKING LOTS from view of the ADJACENT STREETS/ROADS. Berms may vary in height, depending on location and proximity of existing trees, but shall have smooth transitions from the top of the curb to the SETBACK line so as to not create snow traps. Grading of berms shall not be lumpy or abrupt.
3.
Landscaping techniques shall be used to alleviate the harsh visual appearance that accompanies PARKING LOTS. At least seventy-five percent (75%) of the length of the frontage of the PARKING LOT must be effectively SCREENED.
4.
Loading, service, or storage areas shall be SCREENED with an opaque screen that is an integral part of the BUILDING architecture. Chain-link fencing with slats, fabric, or pallets is not an acceptable screening material. Plant material shall be used to soften the appearance of the screen.
C.
Landscaping requirements along roadway corridors.
1.
Plantings along roadways shall be integrated with the landscaping of the rest of the site.
2.
A minimum LANDSCAPE SETBACK in accordance with Table 23.5 below shall be included, to be measured from the existing or future RIGHT-OF-WAY at right angles to the STREET/ROAD towards the interior of the LOT. The LANDSCAPE SETBACK shall include five (5) shrubs (minimum size of five-gallon container) plus either one (1) shade tree with a minimum two-and-one-half-inch-caliper (measured six (6) feet above the surrounding ground) or one (1) coniferous tree with a minimum height of six (6) feet for every forty (40) feet of STREET/ROAD frontage. A mix of coniferous and deciduous trees and shrubs shall be clustered or grouped to avoid straight lines, with a maximum distance of one hundred (100) feet between trees or groupings. The effectiveness of the screening along I-25 and State Highway 119 shall be increased by planting trees and shrubs in layered beds (two (2) or more rows of plant material rather than a single row). No parking, storage, fencing, or other STRUCTURES shall be permitted within the LANDSCAPE SETBACK.
Table 23.5
I-25 Overlay District Landscape Setbacks
D.
General landscaping standards.

The Director of Planning Services may grant a one-time extension of up to one hundred twenty (120) days, for good cause shown, upon a written request by the landowner.
(Weld County Code Ordinance 2020-15)
Located within the A (Agricultural) Zone are properties listed on the National Register of Historic Places and recognized by resolution of the Board of County Commissioners of Weld County as "Agricultural Heritage Sites." Agricultural Heritage Sites may be owned by private citizens, private corporations or by non-profit corporations. The National Register of Historic Places listings recognize that the Agricultural Heritage Sites have historic significance typically because of a long and unique history of agricultural activities having taken place thereon. The Board of County Commissioners finds that Agricultural Heritage Sites must be preserved for future generations and not be subject to eminent domain proceedings brought by Weld County intending to acquire rights-of-way for road improvements, unless such acquisitions are agreed to by the owners of the Agricultural Heritage Sites.
The purpose and intent of the Agricultural Heritage Overlay District shall be to preserve and protect Agricultural Heritage Sites located in the A (Agricultural) Zone and listed on the National Register of Historic Places from eminent domain proceedings brought by Weld County to acquire rights-of-way for road improvements, unless such acquisitions are agreed to by the owner(s) of the Agricultural Heritage Sites.
There is hereby established in the Weld County A (Agricultural) Zone an Agricultural Heritage Overlay District. The Agricultural Heritage Overlay District includes all lands which have been listed on the National Register of Historic Places because of their long and unique history of agricultural activities having taken place thereon and which have been designated as Agricultural Heritage Sites by resolution(s) of the Board of County Commissioners.
All USES permitted within the A (Agricultural) Zone District as Uses by Right, Accessory Uses, permitted uses (ZPAG's), or Uses by Special Review (USR's) shall be permitted on an Agricultural Heritage Site.
For a property located in the A (Agricultural) Zone which is listed on the National Register of Historic Places to come within the Agricultural Heritage Overlay District and thereby authorized to take advantage of the protections detailed in Section 23-5-550, below, it must be designated as an Agricultural Heritage Site by resolution of the Board of County Commissioners.
Agricultural Heritage Sites within the Agricultural Heritage Overlay District shall not be subject to eminent domain proceedings by Weld County to acquire rights-of-way for road improvements, unless such acquisitions are agreed to by the owner(s) of the Agricultural Heritage Sites.
